Fire safety onboard

Fire prevention and preparedness for life afloat

A fire aboard a narrowboat is one of the most dangerous emergencies that can occur. The topic is huge and well worth understanding in detail.

Why fires on boats are so dangerous

Confined spaces mean smoke spreads fast, reducing visibility and oxygen.
Limited escape routes make evacuation difficult.
Flammable interiors (wood, textiles, fuel, gas, batteries) accelerate spread.
Marina proximity can lead to fire jumping between boats.
Environmental harm from burning plastics, fuels and fire suppression runoff.

Fire extinguishers

Fire extinguishers are essential to have onboard, and could be the difference between a close call and a disaster. To get a valid Boat Safety Scheme (BSS) Certificate, your boat must carry the correct type and number of fire extinguishers.

Fire blankets are essential in the galley where they are used to smother pan fires or protect from flames during escape.

Make sure your fire extinguishers and blankets are regularly maintained.

Check pressure, pin, and condition monthly.
Professionally service annually.
Replace or recharge after any use.
Hydrostatic test every 10 years (CO2 types).
Log checks and services in a fire safety record.

Smoke, gas, and CO alarms

Smoke, gas, and carbon monoxide (CO) alarms are absolutely essential on a narrowboat because the risk of fire, gas leaks, and carbon monoxide poisoning is significantly higher in such a small, enclosed environment. Any one of these dangers can turn deadly in minutes if not detected early.

Fire prevention

Fire prevention on a narrowboat starts with regular maintenance and safe storage practices.

Engines should be routinely inspected – check fuel lines, bilges, and hoses for leaks or build up, and keep everything clean to reduce fire risk.
Electrical systems, including solar and shore power connections, should be installed and checked by qualified marine electricians.
Gas systems must be inspected annually by a Gas Safe engineer to ensure there are no leaks or faulty fittings.
Safe storage is equally important: fuel and gas bottles must be kept in ventilated lockers, and charging devices – especially lithium batteries should never be left near exits or left charging overnight.
Avoid non-certified chargers and batteries altogether, and make sure any damaged batteries are disposed of immediately.

Preparing your crew

Fire safety equipment is only effective if your crew:

Knows where it is.
Knows how to use it.
Knows when to evacuate.

Make sure everyone onboard knows:

What to do in the event of a fire.
How to operate extinguishers in order to escape (or fight the fire if confident to do so).
How to shut down gas and electrics (if confident to do so).
How to contact emergency services.
